LUBRICATOR.

To all whom. it may concern:

Be it known that I, ADoLrH RosNnii, a citizen of the UnitedStates,`residing at `4l.- Ventura street, Springfield, in the county ofHampden, State of Massachusetts, have invented certain new and usefulImprovements iii Lubricators 5 and I do'hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.v t

T lie present invention relates to oilers for oscillating devices, suchas oscillating inagnetos, and particularly to one adapted to be carriedby the oscillatory mechanism there Y of. f a

' In accordance with one part of my iiiven tion, thevoiler is carried bythe trip lever of the oscillating mechanism, so that vduring operation,oil is caused by the snap action of the trip lever to be actively fedonto the parts to be lubricated, and during rest the oil feed is reducedto a minimum. yPreferably tlie oiler has means, such as laterallyextending portions, engaging the trip lever for more rigidly holding itin fixed'relation, the lever having, if desired, a squared portion forengagement with such means.

IVhetlier or not the oiler has means for more rigidly holding it inlined relation to the trip lever, but preferably so, the oiler is, inaccordance with another part of my invention secured to the lever by thesaine means used for securing the lever to the sli-aft of theoscillatory mechanism thereby simplifying the installation and making itpossible to install the oiler on present os cillating mechanism withoutmachining or using special tools or parts. t

In the preferred embodiment of the invention describedliereinaftei,'tlie oiler comprises a container having a supporting poi'-tion by which the oiler may be rigidly secured to the trip lever by aysecuring means, the trip lever engaging the means, provided on thesupporting portion, having'means bearing against and supporting thebottoni of the container, thus adding rigidity to the oiler. y f

It is another part of my invention to construct the oiler with acontainerhaving a permanently open top and with oil retaining means, andprovidingthe container with rmeans, preferably in the form' of upwardlyconverging end walls, for retaining theV oil retaining means in place sothat it `will'fnot be Specication'ofLetters Patent.

upwardly'converging end walls, alsohas oil y dripping means,V preferablyin the form, of depending pro]ections, for receiving oil from the oilretaining means and valong which the" l oil may How and from which'dropsof oil may be shaken, during the ,oscillation of,

the trip lever and oiler, thedrops ofoil being cast against the parts tobe lubricated. The oil is preferably .conducted fromf-"the oilietaiiiingmeans to the eXteriorof, the containeigvas to the oil drippingmeansy or depending projections, through open-ings,

preferably in the form of slots,"fprofvided in *theV bottom of the oilcontainer adjacent such projections. 1

As another feature of my invention, I con# struct or compose my oilerfrom a" single sheet metal blank having "portions which when bent andfolded, form the bottom, side and end walls of the container.togetherwith a` supporting portion by which the oiler is ,e i Y securedtothe trip lever, the supporting portions having portions which whenylaterally bent form ythe portions for engaging. the trip lever formaintaining ltheffixed rela- Vtion between the trip lever and oiler, s oas to generally reinforce and give rigidity to thel oiler, drippingportions vbeing also formed integrally with the endwall y.portions.

In the accompanying drawing illustrating a preferred embodiment of' theinvention as applied to an oscillatingmagneto: Figure, 1 is an end viewof an oscillating magneto with an oiler in operative position;

Fig. Qis a fragmentary sectional view taken., on line 2 2 of Fig. l;Fig. 3 is a'yfragmentary s fectional'view taken on .line -lzof Fig. l;Fig. 4 is a longitudinal 'section of the oiler taken on line 4-#4 ofFig.v 3; Fig.

5 is a fragmentary sectional viewA taken on Y line -ro'f Fig. l; Fig.Gis a perspective view of the oiler; and Fig. 7 Vis a plan view of thesheet metal blank in developed form from which the oiler is constructed.

leferringmore particularly tothe 1 ing the magneto 1 has an end plate 2carrying laterally extending arms 3 at the ends of which are pivotallymounted rollers 4 carrying an end of oscillating springs 5, the otherend of the springs being connected to rollers (5 pivotally mounted uponpins 7 rigidlysecured to a yoke portion 8 ofl trip lever 9. VThe triplever has a taperedsoclet 10 fitting with the tapered end 11 of themagneto shaft 12, and is maintained in fixedA rel'- ative position tothe shaft 12 by means of a` nut 13 threaded upon the screw threaded end14 of the shaft, a'suitable spring` lock' washer 15 being convenientlyinterposed between the nut and the trip lever. The trip lever extendsdownwardly a sufficient distance to be engaged by a roller 16 mountedupon a pin 17 carried as a fixed partof a moving member of an engine,such as the flywheel of the engine.l The lower portion 18 of the triplever has a machined surface V19 against'and along which the roller 16contacts Vand moves when the trip lever is shifted from the positionshown in full lines to that. shown in dotted lines in Fig. 1, the roller16 disengaging the end of the portion 18 in the dotted line positionshown.

TheV oiler is constructed from a single sheet metal blank which may becut or formed 'into' shape, as by die-pressing or similar modes ofmanufacture, so as to provide in the sheet side portions 21 and 22, abottom portion 23, supporting portions 2e and 25,end portions 26 and 27,drip portions 28 and 29, formed integral' with the end wall portions,and reinforcingportions 30, 31, 32 and 33, the reinforcing portions,when laterally bent and curved, and adapted to engage with the triplever as well as with the bottom portion of the oiler, in a mannerhereinafter more fullyv described.

In constructing the oiler the blank may be bent or folded along thedotted lines shown so as -to bringy the supporting' portions 24 and'25adjacent each other and the side wall portions 21 and 22 inrspacedparallel relation withV the bottom portion 23 extending from thesupporting' portion 25 to the side wall portion 22 as is clearly shownin Fig. 3. The end portions are also bent or folded so as to providedepending drip portions 28 and 29 at the ends of the oiler andI aremaintained in proper relation by bending or, folding over the flangepori tions 34v and 35 at vthe rear of the side' wall forcing' portions30 and 31, as ywell as por-V tions 32 and 33` are bent laterally fromthe supporting` portion 24: with the portions 32 and 33 suitably curved,and, if necessary, spun into shape', so that theV upper ends of thereinforcingportions 32 and 33 will bear upwardly and against the bottomwall 23 so asv tog-ive rigidityto the oiler as a whole, as will appear`more fully hereinafter.

The supporting' -portions .2f-l and .25 are pro-[\70 comprising themember 24 andV 25 by which the oiler may be secured'in position upon thetrip lever. The depending supportingl portion isprefe 'ably locatedbetween the end ofthe tapered portionll of the shaft 12 and the washer15, the nut 13 constituting' common means forsecuring` the oiler inplace upon the shaft 12 as vwell as for securing' the trip lever uponthe rshaft 12. The trip lever' is. conveniently provided with a squaredportion 37 against the lateral faces of which contact or engage thelaterally extending' reinforcing` portions 30 and 31, which engagementprevents relative angular movement betweenthe supporting;` por# tion ofthe oiler and the trip lever, thereby maintainingl the oiler and triplever 'fixed with the container elevated position above the trip leverso that the depending' drip pingportions will be located above the rolers G and pins 7 for a purpose more fully hereinafter disclosed. Thereinforcing portions 32 and 33 are upwardly curvedl as well asextending' laterally from the supportingportion of the oiler with theupper end of the curved portionsbearing` against and supporting' thebottom 23 of the container so as to give rigidity to the container andto prevent the same from sagging during` its operation.

lV'thin the c i` ntainer is placed ar'suitable oil retaining' means 33of absorbent material such as felt or wick-like ysubstance adapted toretain, by capillary attractiona suitable uantity of oil but to alsopermit aslow ow of the oil therefrom as the oiler is oscilf lated. orgiven a snap actio'n'by the oscillation of the trip lever. rllhe.oilrretaini'ng `means will also act as a filtering means there- .byremoving foreign substances from the oil before the oil 1s conveyed tothe parts to be lubricated.Y rllhe bottom portion 23 of the container ispreferably formed with the ends thereof slightly spaced from the innerfaces of the end wall portions or depending' drip portions'23 and 29,thefs'p'aces thus formed 'l between the'ends of the bottom and the dripportions forming openings 39 in the shape of slots through which oil maybe vconducted from the oil retainingrmeans in the conmechanism to belubricated. The oil retainl ing means is pressedpinto -position andslightly compressed at the ends by the upwardly converging end wallportions 26 and 27, the inclination-of the latter being of utility toprevent the workingof the oil retaining means out of the container andfrom being loosened or thrown from the container during action of thetripping mechanism.

` t will be observed that the container is located above the yoke 8 andthe trip lever in such position that the lowermost point of the drippingportions 28 and 29 will lie substantially in the vertical plane passingbetween the inner surface of the4 rollers 6 and the adjacent surface ofthe yoke 8 so that the oil will fall or drop onto these members and willwork its way between these surfaces as well as upon the bearing surfaceof the pins 7 and rollers 6 to lubricate the same. Oil willcontinue toflow along the trip lever to the lower end thereof and along the surface19 lubricating the same for contact with the roller 16 carried by theengine flywheel. In this way lubrication of-several points by a singleunitary device is continuouslyobtained during the operation of theoscillating mechanism.

It will also be observed that the oil container has a permanently openedtop and is elongated so that the oil may be poured into the containerupon the oil retaining means at any time, especially when theoscillating mechanism is in operation. The oil will seep through the oilretaining means and gradually flow through the openings or slots 39 ontothev drip projections from which the drops of oil may be snapped orthrown upon the parts to be lubricated during the oscillation of thetrip lever and the oiler.

In operation the roller 16, carried by a moving part of the engine, suchas a flywheel, contacts with the surface 19 of-'the trip lever, causingsaid lever to be shifted from the position shown in full lines to thatshown in dotted lines, in Fig. 1 of the drawing, during which time theShaft 12, carrying the oscillating armature of the magneto, is given acertain angularly movement,'and the springs 15 are tensioned by reasonof ythe rollers 6 and pins 7 being angularly moved about the axis of theshaft 12 to a point where the roller 16 disengages with the end of thetrip lever, whereupon the springs', due to their contractile effect,suddenly oscillate the trip lever in reversed direction, the oiler beingalso oscillated simultaneously, since it isrigidly secured in fixedrelation to thetrip lever. This snap action, due to the oscillation ofthe trip lever 'I and oiler, will aid the oil'to flow from the containeronto the drip' projections and will also cause the drops of oil adheringtothe drip projections to be cast therefromiand upon'the parts to belubricated, such as .the

surfaces'between the rollers 16, yoke 8 and pins 7, the oil eventuallyflowing down along the trip lever to the surfacei19, thus lubricatingsaid surface for contact therewith of the roller 16. Vhen the operationof the de vice ceases Ythere is no tendency for the oil to be thrownfrom .the container and the oil retaining means will retain the oil, bycapillarity, with a minimum loss.
